摘要
传统的变电站控制测量采用三角测量、导线测量及卫星定位测量,通常现场需要 2 个及以上人员和大量的测量仪器,而且传统的控制测量方法耗时耗力,在工程任务工期和人员紧张的情况下,较难满足要求.介绍一种在变电站控制测量中使用的快速投影变形计算方法,该计算方法以选定的投影原点将控制网中其他控制点投影到目标投影高,以达到快速控制投影的目的.这种快速投影方法较传统的控制测量方法更为高效,为变电站全过程测量"单兵作业"模式提供新的作业方法.
Abstract
Traditional substation control surveying and mapping adopts triangulation,traverse surveying and satellite positioning surveying,which usually requires two more personnel and a large amount of surveying instruments on site.Moreover,traditional control surveying methods are time-consuming and labor-intensive,making it difficult to meet re-quirements when the project schedule and personnel are tight.This paper introduces a rapid projection deformation cal-culation method used in substation control surveying.This calculation method projects other points in the control network to the target projection height by selecting a projection origin,thus achieving the purpose of rapid control projection.This rapid projection method is more than traditional control surveying methods,providing a new working method for the"single soldier operation"mode of substation full-process surveying and mapping.
